HZD coaxial self-priming acid alkali pump

1. Using FRPP and PVDF materials for injection molding, it has strong corrosion resistance, strong acid and alkali resistance.

2. Applicable temperature: below FRPP-65 ℃, below PVDF-90 ℃.

3. Unique shaft seal design, adopting self cooling design, without the need for external cooling.

4. Self suction design: Strong self suction and check valve design, allowing liquid to flow back into the house pump.
